Raise High the Roof Beam, Carpenters - J.D. Salinger
My last guest had evidently let himself out of the apartment. Only his empty glass, and his cigar end in the pewter ashtray, indicated that he had ever existed. I still rather thing his cigar end should have been forwarded on to Seymour, the usual run of wedding gifts being what it is. Just the cigar, in a small, nice box. Possibly with a blank sheet of paper enclosed, by way of explanation.
